Hello, Jeno9, and welcome to the Simple English Wikipedia!
You should begin by reading these pages:
If you want some ideas of which pages to work on, read Wikipedia:Requested articles or the list of wanted pages.
Remember to be bold and edit any pages you want! Any changes you make that are not perfect can be fixed later. If you have any questions, ask them at Wikipedia:Simple talk. You should always sign your messages on Talk pages by typing "~~~~" (four tildes) at the end of your words.
Good luck and happy editing! Gwib -(talk)- 20:26, 5 August 2008 (UTC)
